Quick-hardening waterproof ceramic tile adhesive

Abstract

The invention provides a quick-hardening waterproof ceramic tile adhesive which comprises powder and liquid. The powder is prepared from, by weight, high-alumina cement, ordinary Portland cement, gypsum, silica sand, silica fume, a water repellent, a water reducer, coal ash, a water retaining agent, an anti-sagging agent, redispersible powder, a water soluble organic compound early strength agent and an alkyl carboxyl retarder; the liquid is prepared from, by weight, an acrylic emulsion, butylbenzene emulsion, water, a defoaming agent and a corrosion remover. According to the adhesive, the powder is formed by combining the ordinary Portland cement, the high-alumina cement and the gypsum and the liquid formed by combing the acrylic emulsion and the butylbenzene emulsion are matched for use, quick-hardening and waterproof effects of the ceramic tile adhesive can be achieved, and compared with an adhesive only adopting powder, the quick-hardening waterproof ceramic tile adhesive is better in adhesion effect and waterproof effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fast-hardening waterproof tile adhesive. Background technique [0002] Tile adhesive is a powdery mixture composed of cement, mineral aggregates, and organic admixtures. When used, it needs to be mixed with water or other liquids to paste ceramic tiles, face tiles, floor tiles and other decorative materials. In the prior art, especially when it is used in places such as interior and exterior walls, bathrooms, etc., due to environmental reasons, the adhesive strength between the ceramic tile and the substrate is seriously affected, resulting in reduced adhesive strength, hollowing, cracking, and ceramic tiles have fallen off. [0003] In the prior art, CN102503303A discloses a high-strength tile adhesive. Although the prepared adhesive has high strength, it takes a long time to harden and is not suitable for rapid construction; the material has high rigidity and low f...

AI Technical Summary

Problems solved by technology

In the prior art, especially when used in interior and exterior walls, bathrooms and other places, due to environmental reasons, the adhesive strength between the ceramic tile and the substrate is seriously affected, resulting in reduced adhesive strength, hollowing, cracking, and tiles have fallen off

[0003] In the prior art, CN102503303A discloses a high-strength tile adhesive. Although the prepared adhesive has high strength, it has a long hardening time and is not suitable for rapid construction; the material has high rigidity and low flexibility

CN103613347A discloses a waterproof tile adhesive material. Although it has good waterproof performance, it still has a long hardening time and is not suitable for rapid construction; the material has high rigidity, low flexibility and low strength, and cannot meet high strength requirements

[0004] CN105503106A discloses a fast-hardening high-strength ceramic tile adhesive, which does not use a liquid agent, so that the bonding strength of the adhesive is still not high, and the waterproofness is also poor, especially difficult to meet the strength and waterproof requirements of wall tiles
